thanks Cloudy.
They say all Geeks are interested in this day Thanks for sharing.
"Every geek knows that F(n)=F(n-1)+F(n-2) is the greatest of all sequences, the Fibonacci Sequence. We all know the Fibonacci sequence is 0,1,1,2,3,5,8,13,21,34,55,89,144,... It is simply adding the preceding number to the current number to get the next number. It was rediscovered in the early 1200's by Leonardo of Pisa, but people in India had discovered it long before."
